Universe as a dodecahedron?: two decades later

I encountered a link to a popular article in Physics World with the title “Is the Universe a dodecahedron” (see this) telling about the proposal of Luminet et al that the Universe has a geometry of dodecahedron. I have commented on this finding almost 20 years ago (see this). A lot has happened during these two decades and it is interesting to take a fresh TGD inspired view.

In the TGD framework, one can imagine two starting points concerning the explanation of the findings.

1. Could there be a connection with the redshift quantization along some lines (“God’s fingers”") proposed by Halton Arp (see this) and Fang-Sato. I have considered several explanations for the quantization. In TGD cosmic=time constant surface corresponds to hyperbolic 3-space H³ of Minkowski space in TGD. H³ allows an infinite number of tessellations (lattice-like structures).

I have proposed an explanation for the redshift quantization in terms of tessellations of H³. The magnetic bodies (MBs) of astrophysical objects and even objects themselves could tend to locate at the unit cells of the tessellation.

So: could the gravitational diffraction of CMB on a local crystal having the structure of icosa-tetrahedral tessellation create the illusion that the Universe is a dodecahedron? Could the possible dark part of the CMB radiation diffract in local tessellations assigned with the local MBs?

1. In diffraction, the wavelength of diffracted radiation must correspond to the size of the unit cell of the lattice-like structure involved. The maximum wavelength of CMB intensity as function of wavelength corresponds to a wavelength of about .5 cm. Can one imagine a tessellation with the unit cell of size about .5 cm?
2. The gravitational Planck constant ℏ_gr =GMm/β₀, where M is large mass and m a small mass, say proton mass (see this, this, this, this and this). Both masses are assignable to the monopole flux tubes mediating gravitational interaction. β₀=v₀/c is velocity parameter and near to unity in the case of Earth.
3. The size scale of the unit cell of the dark gravitational crystal would be naturally given by Λ_gr = ℏ_gr/m= GM/β₀ and would be depend on M only and would be rather large and depend on the local large mass M, say that of Earth. Λ_gr does not depend on m (Equivalence Principle).
4. For Earth, the size scale of the unit cell would be of the order of Λ_gr= GM_E/β₀ ≈ .45 cm, where β₀= 0=v₀/c ≈ 1 is near unity from the experimental inputs emerging from quantum hydrodynamics (see this) and quantum model of EEG (see this) and quantum gravitational model for metabolism (see this and this). Λ_gr could define the size of the unit cell of the icosa-tetrahedral tessellation. Note that Earth’s Schwartschild radius r_S=2GM≈ .9 cm.

Encouragingly, the wavelength of CMB intensity as a function of wavelength around .5 cm to be compared with Λ_gr ≈ .45 cm! Quantum gravitational diffraction might take place for dark CMB and give rise to the diffraction peaks!
